That's it I had to ask...

That's it I had to ask...

I have seen all over the net on how to reverse your lens for macro
photography. This is what I have learned...

Take a 18-55mm lens and take a 50mm lens put the 18-55mm lens
on the camera and the 50mm lens facing the 18-55 mm lens.
OPEN WIDE the 50mm and focus....on and on

I tried it all holding the lens far,close everywhere. (handheld which I read is
very possible). It just does not focus!!!

IIRC to focus using the reversed lens technique, you simply move the camera-lens apparatus back and forth towards and away from the subject.

In the days of manual focus SLR's (Geez, I feel old) Pentax, and I assume other manufacturers, sold "reversing rings". These allowed you to mount a 50mm lens backwards on the body and it made an excellent macro lens with 1:1 magnification in most instances. You focussed by moving back and forth.

I took 2 unwanted filters, removed the glass and epoxied them together.

You can buy double filter rings to accomplish the reversing of a lens on the front of another, or make your own as JC did.

You can also buy K mount reverse adapters that click into the mount. Then you screw the lens onto the adapter using the front filter ring and step up/down rings as needed. I used a 28/3.5 on a 52mm reverse adapter + 49/52 step down for many years. Now I have a macro that works more easily.

NYpHoToGraphEr,
I tried your setup with limited success. I don't think that zoom lenses are suited for macro myself. The 18-55 was set to manual focus at f5.6 and 55mm. The 50mm was at f2.0 try to minimize vignetting. Sutter speed was 125 and the SR on, hand held. Depth of field was shollow and working distance very very close. Here is a shot. It will work with a pair of primes much better.

Get some extension rings. Make every lens a macro lens.
